Particle number fluctuations in the quasiparticle random-phase approximation and renormalized quasiparticle random-phase approximation

Article 1998 EN

Particle number fluctuations in the quasiparticle random-phase approximation (QRPA) and the renormalized quasiparticle random-phase approximation are investigated. A closed expression for the ground state wave function is used, which allows an exact evaluation of the ground state phonon number and correlation function, being valid to any order in the backward amplitudes. In realistic calculations…
